论述了泗阳抽水发电站技术改造的主泵水力模型选择和模型试验结果分析,试验分析表明:选用比速900的模型,在只需更换叶轮和导叶体的情况下,抽水流量至少可增加20%,而发电出力可提高50%.
The hydraulic model selection and model test results of the main pump in Siyang Pumping Station are discussed. The experimental results show that the pump flow rate can be increased at least when the impeller and guide vane are replaced by the model with specific speed of 900 20%, while the power output can be increased by 50%.
